This is a 1973 GMC (same as Chevy) Suburban Sierra Grande, known to many as the "Macho Grande." This is the Suburban you've seen in Episode 8 and Episode 25 of the show called "Roadkill" on the Motor Trend channel of YouTube. Search "Roadkill Episode 8" on YouTube and you'll see a lot of footage of this truck. I should make it clear that this sale is from a private party, and not from Roadkill, Motor Trend, or the parent company, TEN. The truck is a two-wheel-drive 3/4-ton with a 454 big-block engine and a TH400 automatic transmission. It runs and drives very well, with all the mechanical stuff functional. According to the previous owner, who had the Suburban for 20-plus years and used it daily, it has 350,000 miles on it, and the engine and trans were rebuilt long ago. The engine has an Edelbrock carb, Edelbrock Performer intake, and Tri-Y headers that are probably Thorleys. It has enough minor oil leaks to leave a drip the size of a quarter overnight and it smells like burning oil when you drive it because it's on the header. The exhaust is in really good shape. The truck has front and rear air that is cold, though the front fan only barely blows. The previous owner changed all the air-conditioning hoses front to back. The cruise control also works. Since I have had it, I've installed a new alternator, plug wires, plugs, radiator, and brake pads. It also has 33-inch Mickey Thompson ATZ radial tires with maybe 3,000 miles on them and lots of meat left. The most annoying thing is that it will kill the battery overnight if you leave it connected, and I have not been able to find the draw. It has a trailer hitch and a trailer brake controller, and you can see in the Roadkill episode that we used it to tow a '55 Chevy from Los Angeles to Oregon and back. The rear springs are saggy, but it works. We got 10 to 7 mpg towing. The interior is pretty torn up, but the door panels are good. The body is amazingly rust-free; you can see a little orange bleed-through in the photos, but it comes off with Comet and a scrubby sponge. There's no rot-through anywhere. The body does have a lot of little dents, which you can see in the photos. The paint is all original except a very old touch-up on the driver door. Overall, this is a great daily truck as-is, and could be made even better if the front a/c fan would blow hard. I'd drive this cross-country right now. The only reason I'm selling it is that the fleet is just too large and expensive to store.

On Jul-04-14 at 12:55:13 PDT, seller added the following information:

ALSO, I have a set of tan barn doors and most if not all of the hardware to install them. I'll throw them in with the Suburban if you want them.

2018 GMC Sierra 2500HD All Mountain concept: Nothing stops it in its tracks

Wed, Nov 22 2017

Winter may not be the best time for sports cars, but snow and ice can still provide a ton of fun in the right vehicle. The Porsche Macan GTS I had back in January was a riot in the snow, and it was wearing nothing more than a good set of winter tires. What you really need to conquer the frozen north is tracks. These replace wheels with the same sort of equipment that helps tanks and snowmobiles roll over damn near everything in their paths. That's what makes the 2018 GMC Sierra 2500HD All Mountain concept so awesome. That and the 910 pound-feet of torque from the 6.6-liter Duramax turbo diesel V8. The All Mountain concept is set to debut this week in Veil, Colorado, home to ski slopes, log cabins and nearly year-round snow pack. The truck is based off a standard GMC Sierra 2500HD. The turbo-diesel V8 makes 445 horsepower in addition to the mountain of torque. Power is sent to all four corners through an Allison 1000 six-speed automatic. The new treads come courtesy of Mattracks. The 150 Series tracks aren't cheap — well into five figures with installation Â— but they give you a nice 16-inch surface at each corner. Other changes and add-ons include graphics on the bodywork, a RIGID E-Series 30-inch light bar, LEDs on the wheel well and underbody, Thule snowboard racks, a roll-up tonneau cover and a new speaker system from Kicker. The truck will stay on display in Veil all winter, though a similar concept will be making its way to various auto shows, starting with Los Angeles next week.

Spy photos suggest more rugged GMC Sierra HD AT4X is on the way

Mon, Mar 21 2022

Ford has the Super Duty Tremor. Ram has the Power Wagon. GM doesn't yet have a really serious heavy duty pickup off-roader, but these spy shots suggest that may be changing. They show a GMC Sierra HD with plenty of height, chunky tires and a prominent skid plate. We suspect it may be an AT4X trim, to slot above the somewhat trail-oriented AT4 already on sale. Despite the heavy camouflage on each end, we can see right away that this GMC has a new front bumper that's turned up at each end, likely to leave some space for getting tires up to obstacles. There doesn't appear to be the air dam that shows up on all other Sierra HD models, either. Under the front end is a very prominent skid plate. Other interesting aspects include the tires. They appear to be the same model of Goodyear Wranglers used on the Chevy Silverado 1500 ZR2, and not the ones currently in use on the Sierra HD AT4. Also, this extra rugged Sierra features a huge exhaust tip, which seems to confirm the Duramax turbodiesel V8 will be available, probably as an option over the gas V8. This is noteworthy since the Ram Power Wagon is only available with a gas engine. Of course the Ford Super Duty Tremor is available with both gas and diesel engines. The regular Sierra 1500 AT4X was only just revealed last October for the 2022 model year. So we would expect that this heavy duty version would make an appearance for either the 2023 or 2024 model year of the model. It could accompany a light refresh of the truck, again similar to the lighter duty model. We expect it will also feature some additional suspension and drivetrain upgrades to help it compete with the Ford and Ram off-roaders. Related video: This content is hosted by a third party.

GM recalling Silverado and Sierra HD diesel pickups over fuel gauge follies

Fri, 03 Jan 2014

General Motors is recalling 9,733 of its heavy-duty twins over concerns with their 6.6-liter diesel engines and dual fuel tanks. The recall covers some Chevrolet Silverado HD and GMC Sierra HD pickups from model years 2012 and 2013, although the exact dates that the recalled trucks were built isn't specified. There's also no mention of how many models come from Chevrolet and how many are from GMC.
The problem rests with the transfer pump responsible for moving fuel from the rear tank to the front tank - it could fail, resulting in an inaccurate fuel gauge. It hardly requires explaining, but a faulty fuel gauge could leave drivers in a situation where they run out of diesel.
GM will begin notifying customers of affected vehicles, who will be asked to report to their dealers for a free replacement transfer pump.
